Yuav tseg cov lus qhia tau siv nyob rau hauv high -} Qhov chaw ib puag ncig?
TauQhia Ntawv QhiasSiv rau hauv high -} Qhov chaw ib puag ncig? Qhov no yog lus nug ntau tau nug los ntawm ntau tus neeg siv khoom. Raws li cov chaw tsim khoom tshwj xeeb hauv R & D thiab muab cov kev qhia tawm ntawm txoj kev qhia, peb tau pom thaum muaj cov neeg siv khoom ua kom zoo txog qhov siab ntawmQhia Ntawv Qhias. Qee tus neeg ntseeg tias "cov qauv kev qhia tuaj yeem tiv thaiv txhua yam kub," ua rau cov lus qhia thaiv jamming thaum siv ncaj qha- huab cua sov. Lwm tus overestate qhov cuam tshuam ntawm kev cuam tshuam ntawm tshav kub, tsis tsim nyog xaiv cov tshwj xeeb tshwj xeeb cov kev coj uas cov khoom pov tseg. Seb cov lus qhia tawm tau ua haujlwm tuaj yeem ua haujlwm hauv high-} qhov chaw ib puag ncig tsis yog qhov yooj yim "yog lossis tsis muaj" lus teb. Nws nyob ntawm qhov sib thooj ntawm cov khoom siv cov khoom, cov qauv siv roj, cov qauv sib khi, thiab cov xwm txheej kub tshwj xeeb.
Kev txuam tsis raug yuav ua rau hnav kom nrawm dua thiab txo lub neej ntawm qhov zoo tshaj plaws, lossis ua rau kis tau cov khoom tsis zoo. Hnub no peb yuav meej dissect kev ua haujlwm, txuam nrog cov kev daws teeb meem, thiab kev ceev faj rauQhia Ntawv Qhias nyob rau hauv high - qhov chaw ib puag ncig.
Ua ntej: qhov "kub siab ua hauj lwm ntsuas" ntawm cov kab lus qhia tawm: kev hloov kho rau cov xwm txheej sib txawv
Lub siab - kub tiv thaivQhia Ntawv QhiaS Tswv yim nyob ntawm cov "kub tsis kam ntawm cov khoom siv hluav taws xob" thiab "kub tsis kam ntawm cov khoom siv (lubrication, sealing)."
Cov kub kub sib txawv yuav tsum muaj kev sib haum xeeb:
1. Nruab nrab {-}} kev kawm qib kub (80 DEGREE -200 Qib): Qhov "tswj tau ntau" rau cov qauv qauv
Feem ntau cov lag luam siab -}} qhov kub thiab txias (piv txwv li, cua sov socing peripheral drives). Lub hom phiaj Qhia Ntawv QhiaS ua tau qhov no los ntawm kev txhim kho lubrication thiab sib khi. Piv txwv li, qhia txog cov kab zaub mov noj, tau muab cov tshuaj fluororububber, ua haujlwm ntawm 160℃rau ib xyoos uas tsis muaj lub taub hau roj hmab tsis ua haujlwm nyob hauv peb lub hlis.
2. High {{{{{- qhov chaw dej khov (200℃-400 degree): yuav tsum tau "cov ntaub ntawv tshwj xeeb + kev cai tsim"
Cov cua txias tshaj 200℃(piv txwv li, cov cuab yeej ua kom tseem ceeb nyob rau hauv cov lus qhia cov lus qhia cov ntaub ntawv thiab cov khoom siv, tsim nyog kev teeb tsa:
Tshav kub dissipation kev pab:Thaum cov chaw kub txog qib 400 degree, ntxiv cov txheej txheem txias zoo li tshav kub disses ntawm sliders kom txo qis kub los ntawm 30% -50%. Cov lus qhia qhia txog cov kab ke ntawm cov iav sib txuas cov tshuab hluav taws xob qis dua ntawm 400℃rau hauv qab 300℃lub neej pabcuam.
Thib ob, "tsis muaj kev pheej hmoo" ntawm linear qhia kev nyob rau hauv high - kev ntsuas ntsuas kub
1. Cov khoom ua rau kev ua haujlwm: Hardness poob thiab oxidation corrosion
Kev pheej hmoo manifestation:Txheem SUJ2 Hlau Cov Khoom Taw Qhia Tseem Ceeb Tshaj Plaws Lub Hardness txo qis dua 2500 Degree →
2. Lubrication tsis ua haujlwm: grease carbonization thiab poob
Kev pheej hmoo manifestation:Cov pa roj ua kom zoo nkauj thiab xau dej siab tshaj 120 degree, carboning rau hauv ib qho nyuaj crust saum toj 180 degree. Qhov no tsis tsuas yog tshem tawm lubrication tab sis kuj txhaws swb cov ntsia hlau, ua rau pom kev.
3. Foob cov qauv teeb tsa: Foob ntiv nplhaib thiab hmoov av intrusion
Kev pheej hmoo manifestation:Roj Hmab Roob Rings pib rau hnub nyoog thiab harden saum toj no thiab harden saum toj no 120 degree, tawg saum toj no 150℃thiab poob kev sib tw ua haujlwm. Siab -} Cov plua plav kub (piv txwv li cov hmoov av tsis sib xws, ua rau "abrasive hnav" thiab nce nqi los ntawm 5-10 zaug.
Kev ntsuas kev ntsuas ntsuas:Nquag huv hmoov av los ntawm kev qhia cov ciav hlau kom tiv thaiv kev sib txuam nkag mus rau cov swb. Rau 200℃metallurgical cov khoom siv kev tsheb ciav hlau, txhim kho cov hmoov av hlau txo cov plua plav hauv 90% thiab swb swb hnav los ntawm 60%.
Peb. Daim Ntawv Qhia Tawm Xaiv Xaiv cov piv txwv rau kev sib txawv siab- kub kev lag luam
1. Kom qhuav thiab cov khoom ci (80℃-150 degree)
Cov Lus Qhia:Tom qab siv cov kev teeb tsa no, cov khoom noj kom qhuav tsis tu ncua ntawm 120℃rau 8,000 teev. Slider hnav yog 0.006mm, txoj kev raug ua kom yog ruaj khov nyob rau ± 0.018mm, uas tsis muaj teeb meem lossis cov teeb meem tsis ua haujlwm. Saib xyuas cov kis txuas ntxiv los ntawm 3 txog 6 lub hlis.
2. Metallurgical Rolling Mills (200 Degree -300 Qib)
Cov kev xaiv cov specifications: Qhia kev tsheb ciav hlau ua los ntawm Inconel 718 siab {} Cov plua plav dawb (}
Piv Txwv Piv Txwv:Tom qab kev txhim kho cov lus qhia no rail hauv lub kub dov zeb, nws ua haujlwm rau 6,000 teev ntawm 280℃nrog tsuas yog 0.009mm hnav. Nws withstood 10kn lub nra hnyav tsis muaj deformation, tiv thaiv hlau oxide nplai plua plav los ntawm 80% piv rau cov qauv qhia cov qauv.
3. Iav Taus Khoom (300 Degree -400 Qib)
Xaiv cov khoom tshwj xeeb:
Coj tus ciav hlau ua los ntawm zirconia ceramic (sab saum toj no ra tsawg dua lossis sib npaug rau 0.1μm),
Cov nplais txiav nruab nrog cov yas ceramic rolling (kom tiv thaiv cov hlau nplaum hlau ntawm qhov kub siab),
Ua -} hauv dej txias dej raws (inlet dej kub 25 degree, qhov hluav taws xob dej tsawg dua lossis sib npaug rau 80 degree),
Foob - ywj pheej tsim (plua plav - pub dawb hauv ib puag ncig).
Lub ntsiab
Tus yuam sij rau high - kubQhia Ntawv QhiaKev ua tau zoo nyob ntawm cov lus dag hauv "Qhov kub thiab txias nrog kev teeb tsa":
{{0- 80℃-200 degree: qib txheem: qib siab {{{} Lubrication + Cov Fluorububub
- 200℃-400 degree: cov ntaub ntawv tshwj xeeb (siab} kub alloys allys) + cua tshuab li qub
- >400 degree: customized tshwj xeeb cov lus qhia (ceramic + Levagetic Levitation). Qhov muag dig muag cov kev sib tw txheem txheem los yog overinvesting nyob rau hauv high- Tus nqi kev teeb tsa tsis muaj kev pheej hmoo tsis muaj peev xwm.
Raws li cov khoom xa khoom, peb qhia kom meej peb cov tsis tau xaiv ua ntej xaiv: Kev ua haujlwm ntsuas kub (tsis txhob muaj kub), thauj khoom thiab nrawm nrawm (thiab ib puag ncig cov plua plav). Match cov ntaub ntawv, lubrication, thiab sealing daws teeb meem raws li. Thaum tsim nyog, peb muab siab - kub simulation kev kuaj kom siv tau ruaj khov, txhim khu kev qha, thiab tus nqi zoo hauv kev kub.
